Many of you are eager to update your smartphone’s operating systems as soon as possible, but this may be the right time to reconsider. Android 8.0 Oreo on Samsung Galaxy A3 (2017) has been reported to cause numerous reboots and bootloops for some – mind you, not all – users. Reboots are reportedly occuring when connecting to some Wi-Fi networks; bootloops are seemingly random. If your device gets into a bootloop, all that you can do is take it to a support center, where it will be recovered through data-wiping recovery. Ouch.
ETA of the fix is currently unknown. Install the update at your own risk.
